TIE PLATE. APPLICATION FILED JUNE12,-197.

Patented De@ E., w08.

Aclose contact with the said base-flange. In

other words, the lower parts of the rib, while being continuous with the higher parts and vforming therewith a rib extending substantially vacross the entire width of the plate, and affording a shoulder having ample bearing surface to receive the outward pressure of the rail, are at the saine tiine so arranged .that they will not interfere with the engageinent of the spike-heads with the base-flange of the rail when the spikes are driven. This feature is clearly illustrated in Fig. 3, where'- in D indicates the tie, E thebaseilange of the rail and F a spike which is driven through the spike-liole with the head in contact with. the top of the base-flange E.

'Fig G shows a narrower 'tic-plate (l having two marginal, longitudinal depending flanges G1 G'L and two intermediate iianges G2 Gf, and a transverse rib H having higher and lower parts arranged reveisely to those of the rib shown in Figs. l to 5. Said tieplate G has three spike-holes I Il l1 one of which, I, is located centrally of the end of the plate in line with the rib H, and the said rib has two rounded, elevated portions It -i adjacent to the side inargins of the plate and an intermediate, lower portion h1 through which extends the spike-hole I.

A rolled metal tie-plate having flanges on its lower surface, grooves in its upper siii'- face'in line with the flanges, and a transverse rib on itsiiipper surface to form a rail-abutting shoulder, said rib consisting of a plul'ality of unwardl y rounded projections separated froin eachother by depressed portions corresponding in location with said grooves,

which projections are of unequal height, has the advantage that the higher projections n'iay be inade toextend a distance above the upper face of the plate suilicient to afford a shoulder of ainple vertical depth to give a reliable -bearing vsurface for,the edge of the rail base-Hange, while at the saine time such a rib with rounded projections may be easily formed on the plate in the operation of rolling. The metal which forms said transverse rib, as a whole, is obtained in the rolling operation by displacement endwise of the metal of the plate, f

while the metal to forin the higher projections is displaced laterally of the plate, or endwise of the rib, the lower connecting parts of the rib, by which the saine is inadeteoi'i.n

tinuous, permitting such lateral displacement of the inetal. In other words, in the rolling operation snilicient inetal is displaced endwise of the plate to niake the rib, as a whole, while the extra quantity of inetal required to forni the higher rounded projections is de rived by lateral displacement -of the nietal froin the parts of the rib having the lower projections and at which the inetal is de- I other by depressed parts so that the rib is, in

effect, continuous and inetal is furnished to forni the higher rounded projection by displacement of the inetal longitudinally of the rib both froin theiparts of the rib at which the lower projections are located and the parts of the rib which are depressed .b etween the projections.

l claim as iny invention Y A tie-plate provided on its iindei surface with a plurality of depending, parallel flanges, and onv itstop surfaeewith a plurality of grooves located severally above and parallel with said flanges, saidplate. being provided with a transverserib forming a rail-abutting shoulder, said rib consisting of a plurality of upwardly rounded projections of unequal height, severa ly located between said grooves and separat "il by depressions in the rib corresponding in location with the said grooves.

In testimony, that I claini the foregoingas iiiy invention I affix iny signature in. the presence of two witnesses, thisrd day of June A. D. 1907.
